Public bug reported:

The issue seems related to the Intel (845G) integrated graphics.  I have
not seen the behavior on other hardware.

In my testing with the Intel driver using its default acceleration:
- Flash 11.2 works on Quantal with the 3.5 kernel
- Flash 11.2 works on Raring with the 3.5.0-17 kernel (though it boots to a low-res desktop with a frozen pointer)
- Flash 11.2 works on Raring also with the 3.6.11-030611 or 3.7.10-030710 mainline kernels
- Flash 11.8 works on Raring with the 3.8 kernel (in Chrome)
- Flash 11.2 fails on Raring with the 3.8 kernel
- Flash 11.2 fails on Raring with the latest mainline kernel, 3.11.0-031100rc5
- Flash 11.2 fails on Saucy alpha 2 with its default kernel

Disabling Flash *hardware* acceleration altogether (via R-click in the
Flash display window: Settings: General tab) did not fix the problem.

Setting the Intel driver's acceleration method to UXA rather than its
default SNA *always* fixes the Flash problem, but causes a garbled login
screen under LightDM that so far has no workaround.

I also tried one possible fix for the default Intel SNA acceleration using the TearFree option.   I created /etc/X11/xorg.conf.d/20-intel.conf with contents:
    Section "Device"
       Identifier  "Intel Graphics"
       Driver      "intel"
       Option      "AccelMethod"  "sna"
       Option      "TearFree"    "true"
    EndSection
But this had no effect.

There was a helpful bug report file against Linux at
http://bugs.launchpad.net/ubuntu/+source/linux/+bug/1178982.
Workarounds posted there were to change the Xorg acceleration method to
UXA, or boot with an older kernel.  The bug was closed only because the
original poster didn't have possession of the machine anymore.
